Foot protection — Perforation resistant inserts
1 Scope
This document provides the classification of perforation resistant inserts, specifies technical requirements and marking, and describes test methods.
This document applies to perforation resistant inserts used in foot protection equipment.
2 Normative references
The following documents contain provisions which, through reference in this text, constitute essential provisions of this document. For dated references, only the edition cited applies; for undated references, the latest edition (including any amendments) applies.
GB/T 3922-2013 Textiles — Tests for colour fastness — Colour fastness to perspiration
GB/T 12903 Terms for personal protective equipment
GB/T 16825.1 Metallic materials — Calibration and verification of static uniaxial testing machines — Part 1: Tension/compression testing machines — Calibration and verification of the force-measuring system
GB 21148 Foot protection — Safety footwear
3 Terms and definitions
Terms and definitions as defined in GB/T 12903, GB 21148 and the following apply to this document.
3.1 Perforation resistant insert
A shoe component placed within the sole assembly (or in close contact with the sole surface) to provide protection against mechanical penetration.
3.2 Tent effect
A phenomenon of interlayer separation occurring during testing where some layers are penetrated while others remain unpenetrated, forming a tent-like arch.
4 Classification
4.1 According to materials, perforation resistant inserts are classified into:
— Metal perforation resistant inserts;
— Non-metal perforation resistant inserts.
4.2 According to protection risk types, non-metal perforation resistant inserts are classified into:
— PL type;
— PS type.
Note: When facing smaller diameters and sharper objects, PS type provides more appropriate protection than PL type.
5 Technical requirements
5.1 General requirements
5.1.1 When no tolerance is specified in this document (text or figures), a maximum tolerance of ±10% shall be applied.
5.1.2 Performance requirements and number of test samples for perforation resistant inserts are listed in Table 1.
Note: This document applies to shoe components rather than complete footwear. When footwear manufacturers select perforation resistant inserts based on test reports according to this document, shoe size compatibility and conformity with overall footwear performance requirements are important reference factors.
Table 1 Performance requirements and number of test samples for perforation resistant inserts
5.2 Dimensions
5.2.1 Each metal perforation resistant insert shall have no more than 3 mounting holes, with each hole diameter not exceeding 3 mm. No holes shall be present in the area from 10% to 52% of the full length measured from the front end (see shaded area in Figure 1).
Explanation of symbols:
L — Full length of metal perforation resistant insert.
Figure 1 Mounting hole positions of metal perforation resistant inserts (example)
5.2.2 Non-metal perforation resistant inserts shall have no holes.
5.3 Penetration resistance
5.3.1 Metal perforation resistant inserts
When tested according to method specified in 6.2.2.1, the penetration force shall not be less than 1,100 N.
5.3.2 Non-metal perforation resistant inserts
When tested according to methods specified in 6.2.2.2 and 6.2.2.3, test results shall meet requirements in Table 2.
Table 2 Penetration resistance requirements for non-metal perforation resistant inserts
5.4 Flex resistance
When tested according to method specified in 6.3 after 1×106 flexing cycles, there shall be no visible cracking, fragmentation or delamination.
5.5 Characteristics of perforation resistant inserts
5.5.1 Corrosion resistance of metal perforation resistant inserts
When tested according to method specified in 6.4, corrosion areas shall not exceed 3 locations, with the maximum new linear length of each corrosion area not exceeding 2 mm.
5.5.2 Stability of non-metal perforation resistant inserts
When tested according to method specified in 6.5, test results shall meet requirements in Table 2.
6 Test methods
6.1 General requirements
6.1.1 Sampling
Number of test samples for each performance shall comply with Table 1.
6.1.2 Conditioning
All samples shall be conditioned for at least 24 hours at (23±2)°C and (50±5)% relative humidity before testing.
6.1.3 Test report
Test report shall include:
— Name and address of testing laboratory;
— Test date;
— Reference to this document (e.g. GB 46308—2025) and clause numbers used;
— Sample information;
— Results required by each test method;
— Deviations from test methods;
— Measurement uncertainty (if applicable).
